King Tut's Secrets: 5 Most Incredible Discoveries of the Week

A new angle on the Bermuda Triangle and a surprise "fairy circle" were among the week's discoveries making headlines:

• 'One of Nature's Greatest Mysteries' Appears in Australia: The fairy circles of Namibia (grassless circles in a honeycomb pattern) were thought to be just in Namibia—until they also turned up thousands of miles away in Australia. The far-away discovery adds weight to one theory about how the circles come to be.
• Hidden Rooms Found in King Tut's Tomb: Nearly 100 years after the discovery of King Tut's tomb, it may be giving up a millennia-old secret: Radar scans of his burial chamber have revealed two hidden rooms. And they suggest the elusive Queen Nefertiti will be revealing some secrets of her own.

• Hiker Finds Incredibly Rare Ancient Coin: Laurie Rimon was hiking in the Galilee area of Israel when she spotted a glint of gold. Amazingly, it was an extremely rare coin minted by Roman Emperor Trajan in AD107, and it may shed light on Rome's military presence there at the time. The coin still has some fascinating iconography.
• Prime Numbers Just Got a LIttle Stranger: Two Stanford mathematicians have managed to surprise others in their field with a previously undiscovered insight about prime numbers: They're not quite as random as believed. One prof not involved with the work sums it up this way: "It's crazy."
• Bermuda Triangle Mystery: Finally Cracked? Norwegian researchers spotted large craters apparently created by methane buildups off Norway's coast, and think gas blowouts could explain the weirdness associated with the infamous Bermuda Triangle region. Unless, of course, the very term "Bermuda Triangle" is a misnomer.
